I use My Book Studio Edition II in Raid 1 configuration as a mirror and use it as a backup storage.
Some time ago, I have lost access to my drive and tried using Windows chkdsk to fix it. I have learned my lesson and I had to configure drive from scratch losing all data.
After working for several months I received error that file is corrupted while trying to access one of the folders.
How can I leverage mirror configuration to restore drive without losing data?
